Seeing a doctor in UK for the first time, yours drug will most likely be a bloody SSRI. Even if your anxiety is so severe that you can talk. Maybe the doctor will be particularly stupid and fall into the marketing that the latest atypical anti psychotic. If you do not have psychotic symptoms DO NOT TAKE AN anti psychotic. It is likely that such a drug will only make your symptoms worse.
Other determinants of resting metabolism include thyroid hormones and catecholamines, genetics, body temperature, and in women, the phase of the menstrual cycle. An increased release of thyroid hormones or catecholamines increases RMR. Conversely, a reduction in energy intake specifically decreases triiodothyronine (T3) levels and norepinephrine release, which can subsequently decrease metabolic rate.
Metabolic rate is a measure of how much food, or fat, is converted to energy in a day. Resting metabolic rate (RMR) is the measurement of how much food, or energy, is required to maintain basic body functions such as heartbeat, breathing, and maintenance of body heat while you are in a state of rest.
